Advanced:
The forecast change indicator type, including temporary, permanent, or probable conditions.  This is an extension of ForecastChangeIndicator that includes report-specific entries, and in particular the 30 and 40% probability conditions.<br /></p><p><br /></p><p>Design note:<br /></p><p>These values represent the operationally-representable types, but are not very general-purpose.  Especially with temporary conditions and probability it might be better to turn these into a "probability" property and constraints could be applied to the value to match operational constraints<br /></p>

  BECOMING

Details:
Notes: When the change is forecast to commence at the beginning of the forecast period and be completed by the end of that period, or when the change is forecast to occur within the forecast period but the time of the change is uncertain (possibly shortly after the beginning of the forecast period, or midway or near the end of that period), the change shall be indicated by only the change indicator BECMG.<br /></p><p><br /></p><p>Enumerations can not inherit from other enumeration types in HollowWorld.  This class duplicates the enumerated types present in WMO ForecastChangeIndicator.<br /></p>
Public
  TEMPORARY_FLUCTUATIONS

Details:
Notes: The change indicator TEMPO shall be used to describe expected temporary fluctuations to meteorological conditions which reach or pass specified threshold criteria and last for a period of less than one hour in each instance and in the aggregate cover less than half of the forecast period during which the fluctuations are expected to occur.<br /></p><p><br /></p><p>Enumerations can not inherit from other enumeration types in HollowWorld.  This class duplicates the enumerated types present in WMO ForecastChangeIndicator.<br /></p>

  FROM

Details:
Notes: The change indicator FROM shall be used to describe expected permanent fluctuations to meteorological conditions.  Forecast conditions given before the FROM group are superseded by the conditions indicated after the group.<br /></p><p><br /></p><p>Annex 3:<br /></p><p>"FROM"<br /></p>
